As my manager says:
Half of the population is more stupid than the other half.
Even if the statement is true, it doesn't really explain why some are more likely to fall for advertisement than others. It's just a cruel fact of life. However if we are in a state of mind where we know that we need something or want something - we are more likely to listen to advertisement.
Some words are better than others in advertisement. We want to feel special, and that it's a bargain or even free, and that someone guarantees that this is a valid product or service and that we get value for money. Have you ever heard that you can "save" money by buying? Thought so, and it's very interesting since you are expected to have more money when you save, not less, which is what happens when you buy something.
But what about the words?
Test the following 30 “magic marketing words” in your next email,
social media or blog post, on a direct-mail postcard or website to see
which yields the best response.
You – Write as though you’re speaking to the customer and about the
customer, not about yourself.
Because – Give customers a reason why
they need to take action.
Free – “Because” we all like free things,
right?
Value – This implies customers are getting something versus
losing something (i.e. money when you say “cost” or “price”).
Guaranteed – Give customers a guarantee to minimize risk perception,
so they feel they have everything to gain and nothing to lose.
Amazing
– Customers will respond to something that is incredible.
Easy – Make
it simple for customers to take the next step in the purchasing
process, and let them know how much easier life will be with your
product or service.
Discover – This implies there is something new and
unknown to the customer, something that has supreme benefits and gives
them an edge.
Act now – Motivate an immediate response with a
limited-time offer.
Everything included/everything you need – This
establishes that your product or service is all your customers will
have to buy in order to achieve their goal.

So we need to have the right words. And we need to place them in the right order:
An effective use of words that is rather unethical but often used in advertising is using logical fallacies. These fallacies, "tricks of the trade," are misleading and are not sound reasoning, based as they are on word choice and syntax rather than evidence. They sound like evidence, but are really lacking evidence.

The technique of advertisement isn't new. There are traces back to 4000 BC, and as long as we sell more products/services by using it, it will be around.
